Detailed Information:
Founded in 1964 by landowners who were threatened by the proposed damming of French Creek, GVA was originally formalized as the French Creek Watershed Association. In 1972, the association expanded to oversee all five of the northern and eastern Chester County's Schuylkill River watersheds, including: Pigeon Creek, Stony Run, PickeringCreek, French Creek and Valley Creek. GVA's area of concern encompasses twenty-one municipalities and one hundred fifty-one square miles. It is the only watershed association in northern Chester County.
